CLIP FOR REINFORCING-BARS FORCONCRETE CON STRUCTION-WORK.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed November 29, 1918. Serial No. 264,699.

To all whom it may concern:

Be it known that I, KENNETH D. STEW- ART, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in-Clips for Reinforcing-Bars for Concrete Construction-Work, of which the following is a specification.

This invention relates to improvements in reinforced concrete construction work, and more particularly to means for holding the reinforcing bars together, as well as for spacing and supporting the same away from the temporary floor, or walls of vertical pouring forms.

For these purposes I provide a metal clip or clamp of such peculiar formation or fabrication as to perform the triple function of tying the bars together, spacing them away from the temporary floor, or walls of vertical work forms, and securely holding them in such spaced relation while the concrete is being poured.

In the accompanying drawing, Figure 1 is a vertical sectional view of a floor, show ing the practical application of my device for securing the reinforcing bars together, and at the same time holding them in spaced relation to the temporary floor or walls of the pouring form; Fig. 2 is a top plan view of the same bars, with my clip attached, beforethe concrete is poured; and Fig. 3 is a view in perspective of my combination clip and support; and Figs. 4 and 5 are modifications of the formation of the leg member.

As shown by the drawing, my device is formed, preferably of one piece or stretch of wire, by first bending it into a relatively long, narrow loop, with its connecting sec tion I) arched slightly upward; each arm a of the loop is then doubled on itself for a certain distance each side of a point intermediate its center, ordinarily substantially at its center, thus forming the two single sections 1 and 2, lying in the plane of the original loop, and the double section, or leg member, 3, disposed at right angles to the plane of the loop; the section 2 is then bent, adjacent its free or outer end, at right angles in the opposite direction from the double section, or leg member, 3, and the portion so bent upward is curved inwardly into sub: stantially a U shape formation or hook 0, the two hooks thus formed over-lapping each other; the lower or outer end of the double section, or leg member, 3 is bent outwardly substantially at right angles to form the foot member (1, designed to rest flatly against. the temporary floor, or Walls of an upright form, through which nails may be driven to hold the bars in place.

If desired, the leg member 3 may be formed by'first turning the wire at its outer end back in the direction from. which it came in the plane of the loop, and then doubling it on itself and crossing the strands at its inner end, as shown in Fig. 4.

Also, if desired, the two strands of the leg member may be twisted upon themselves as shown in Fig. 5.

The clip is attached by first placing the arched connecting section I) over the top bar 6 at one side of the lower or cross bar f, then passing the two arms a a of the clip underneath the last mentioned bar, after which the hook members 0 are sprung over the top of the upper bar.

I claim 1. A device of the class described, comprising a strand of Wire bent at its center into a loop, the connecting section between the two arms of the loop being arched slightly upward, and the outer or free end of each arm being provided with an inwardly turned hook member disposed substantially at right angles to the plane of the loop, and each of said arms being bent downward at a point intermediate its ends and then doubled back upon itself to form a double-strand leg member disposed substantially at right angles to theplane of the loop, the remaining section of the arm being then turned into the original plane of the loop, and the lower or outer end of said leg member being turned outwardly substanlgially at right angles to form a foot mem- 2. A device of the class described, comprising a strand of wire bent at its center into a loop, the connecting section between the two arms of the loop being arched slightly upward, and the outer or free end of each arm being turned upward substantially at right angles, and then curved into an inwardly turned hook member, and each of said arms being bent downward at a point intermediate its ends and then doubled back upon itself to form a double-strand leg member disposed substantially at right angles to the plane of the loop, the remaining section of the arm being then turned into the original plane of the loop, and the lower or outer end of said leg member being turned outwardly substantially at right angles to form a foot member.

3. A device of the class described comprising a strand of wire bent at its center into a loop, the connecting section between the two arms of the loop being arched slightly upward, and the outer or free end of each arm being provided with an inwardly turned hook member disposed substantially at right angles to the plane of the loop, and each of said arms being bent downward at a point intermediate its ends and then doubled back upon itself to form Copies of this patent may be obtained for five cents each, by addressing the Commissionerof Batentst a double strand leg member disposed substantially at right angles to the plane of the loop, the remaining section of the arm being then turned into the original plane of the loop, the strands-0f said leg member being twisted upon themselves, and the lower end thereof being turned outwardly substan tially at right angles to form a foot member.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
